Some byte examples

Here we can see how to create some fixed size tables:

Wiki markup

    {| class="wikitable" style="text-align:center"
!colspan="2" style="width:70px" | Byte 0 !! colspan="2" style="width:70px" | Byte 1 !!colspan="2" style="width:70px" | Byte 2 !!colspan="2" style="width:70px" | Byte 3 !!colspan="2" style="width:70px" | Byte 4 !! colspan="2" style="width:70px" | Byte 5 
|- 
|style="width:35px"| '!' || 0x21 || style="width:35px"| 'b' || 0x62 || colspan="8" style="background:#ABCDEF;" | Argument
|}


{| class="wikitable" style="text-align:center"
!colspan="2" style="width:70px" | Byte 0 !! colspan="2" style="width:70px" | Byte 1 !!colspan="2" style="width:70px" | Byte 2 !!colspan="2" style="width:70px" | Byte 3 !!colspan="2" style="width:70px" | Byte 4 !! colspan="2" style="width:70px" | Byte 5 
|- 
|style="width:35px"| '!' || 0x21 || style="width:35px"| 'b' || 0x62 || colspan="2" style="background:#ABCDEF;" | 0x01 || colspan="2" style="background:#ABCDEF;" | 0x02 || colspan="2" style="background:#ABCDEF;" | 0x03 || colspan="2" style="background:#ABCDEF;" | 0x04
|-
|colspan="2" style="width:70px;" | || colspan="2" style="width:70px" | ||  colspan="8" style="width:280px; background:#ABCDEF;" | Argument
|}

Results

    Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5
    '!' 0x21 'b' 0x62 Argument


    Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5
    '!' 0x21 'b' 0x62 0x01 0x02 0x03 0x04
    Argument


Some bit field examples

Here we can see how to create some fixed size tables:

Wiki markup

    Normal table
{| class="wikitable"
!style="width:35px"| Bit 7 !! style="width:35px"| Bit 6 !! style="width:35px"| Bit 5 !! style="width:35px"| Bit 4 !! style="width:35px"| Bit 3 !!  style="width:35px"| Bit 2 !! style="width:35px"| Bit 1 !! style="width:35px"| Bit 0 
|-
| 0 || 0 || 0 || 0 || 0 || 0 || 0 || 0
|}

Table with highlighed background:
{| class="wikitable" 
!style="width:35px; background:#ABCDEF;" | Bit 0 !! style="width:35px"| Bit 1 !! style="width:35px"| Bit 2 !! style="width:35px"| Bit 3 !! style="width:35px"| Bit 4 !!  style="width:35px"| Bit 5 !! style="width:35px"| Bit 6 !! style="width:35px"| Bit 7
|-
| style="background:#ABCDEF;" | 0 || 0 || 0 || 0 || 0 || 0 || 0 || 0
|}

Table with incomplete cols and centering:
{| class="wikitable" style="text-align:center"
!style="width:35px"| Bit 15 !! style="width:35px"| Bit 14 !! style="width:35px"| Bit 13 !! style="width:35px"| Bit 12 !!  style="width:35px"| Bit 11 !! style="width:35px"| Bit 10 !! style="width:35px"| Bit  9 !! style="width:35px"| Bit  8 !!   style="width:35px"| Bit  7 !!  style="width:35px"| Bit  6 !! style="width:35px"| Bit  5 !! style="width:35px"| Bit  4 !! style="width:35px"| Bit  3 !! style="width:35px"| Bit  2 !! style="width:35px"| Bit  1 !! style="width:35px"| Bit  0
|-
|style="background:#ABCDEF;"| 0x8000 || style="background:#ABCDEF;"| 0x4000 || style="background:#ABCDEF;"| 0x2000 || style="background:#ABCDEF;"| 0x1000 || style="background:#ABCDEF;"| 0x0800 ||  style="background:#ABCDEF;"| 0x0400 || style="background:#ABCDEF;"| 0x0200 || style="background:#ABCDEF;"| 0x0100 || style="background:#ABCDEF;"| 0x0080 ||   style="background:#ABCDEF;"| 0x0040 ||  style="background:#ABCDEF;"| 0x0020 || style="background:#ABCDEF;"| 0x0010 || style="background:#ABCDEF;"| 0x0008 || style="background:#ABCDEF;"| 0x0004 || style="background:#ABCDEF;"| 0x0002 || style="background:#ABCDEF;"| 0x0001

|-
| 0 || 0 || 0 || 0 || 0 || 0 || 0 || 0
|}

Results

    Normal table
    Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
    0 0 0 0 0 0 0 0

    Table with highlighed background:

    Bit 0 Bit 1 Bit 2 Bit 3 Bit 4 Bit 5 Bit 6 Bit 7
    0 0 0 0 0 0 0 0

    Table with incomplete cols and centering:

    Bit 15 Bit 14 Bit 13 Bit 12 Bit 11 Bit 10 Bit 9 Bit 8 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
    0x8000 0x4000 0x2000 0x1000 0x0800 0x0400 0x0200 0x0100 0x0080 0x0040 0x0020 0x0010 0x0008 0x0004 0x0002 0x0001
